Probing Physics beyond the Standard Model with Nucleons.

Precision measurements on nucleons provide constraints on the Standard
Model and can also discern the signatures predicted for particles
beyond the Standard Model. Knowing the Standard Model inputs to
nucleon matrix elements will be necessary to constrain the couplings
of dark-matter candidates such as the neutralino, to relate the
neutron electric dipole moment to the CP-violating theta parameter, or
to search for new TeV-scale particles though non--V-A interactions in
neutron beta decay. Improved algorithms and increased computational
power derived from a diverse portfolio of computer hardware are
now allowing lattice QCD to achieve the precision needed to probe
new physics in the nucleon sector.
In this talk, I will review the progress and prospects for lattice
QCD as a bridge between theory and precision experiments in the
search for new physics in the nucleon sector.
